Ambry Genetics

Nov 09, 2022

The c.163C>A (p.P55T) alteration is located in exon 2 (coding exon 2) of the TMEM17 gene. This alteration results from a C to A substitution at nucleotide position 163, causing the proline (P) at amino acid position 55 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
